I have a 16gb iPhone 5s and a 16gb iPad Mini. Both were down to a little over a gig of free space. I was not worried yet but I was getting close to worrying. Then iOS 8 was released and I installed the 8.0.1 point release that caused so many issues.

In an attempt to downgrade the phone I did a full erase and reset, after backing up of course, and when I did the restore I mysteriously had 5 gigs of free space!!!

At first I suspected the restore had not completed, but after an hour or so of using the phone I was convinced that it indeed had fully restored. So where did the free space come from?

While I am still not entirely certain, my best guess is that apps that I had deleted were not in fact entirely gone. But when I did the full reset followed by a restore they did not come back.

When I upgraded I did so via iTunes not the OTA install. And the space available before and after the iOS 8 install was roughly the same anyway.

So, I decided to test the theory and backed my iPad up. Then did a full factory reset and restore, and poofI I also gained roughly 5 gigs of free space on my iPad!

Not sure how useful this will be to anyone else, but I thought it was interesting!

with the upcoming iphone 7 you don't need to rest your phone to get more space because the new iphone 7 coming out will be 128GB storage , that space is moer than enough for a smartphonesource: http://www.newphones-comingout.com/2015/03/new-iphone-7-coming-out.html
